Why does my heater not change from defrost vents?
Re: Heater/ac will not change from defrost vents to any… Failure of mode and/or blend door operation most often tends to be vacuum supply issues. If there is no operation of the doors at all (switching from defrost-floor-vent) then verify vacuum supply on the vacuum line at entry of the firewall (it’s easiest to get to).

Your thermostat is switched to ON. If your thermostat switch is set to ON, that means the blower will run constantly—even when your system isn’t cooling your home, which will result in warm air blowing from your vents. How to fix it: Switch your thermostat to AUTO (see image below), so air only blows from your vents when the AC is cooling.
What happens if your AC control switch is not working?
The AC control switch is what powers and controls the AC compressor, as well as the entire system.

In most cases a bad or failing AC control switch will display noticeable symptoms that hint…
Why is my AC switch hot to the touch?
It may become hot to the touch and begin to malfunction or not function at all. The switch also distributes power to other AC components. Therefore, a problem with the switch may cause other components to overheat, due to excessive power or heat. Usually when a switch is hot to the touch, it has malfunctioned and needs to be replaced. 2.
Why does my AC not cool hot air?
The chemical Freon or simply you can call it coolant is the reason why the AC cools hot air quickly. The chemical can run out if there is any leakage in the AC. Thus, AC would not work, as there is no Freon in the system. You can handle this situation by using the best maintenance tips.

Are there any thermostats that automatically switch from heat to cool?
There are programmable thermostats that automatically switch from heat to a/c and to heat again. Some Honeywell thermostats, such as the 8000 Series, have ‘auto’ setting where you can program the Heat temperature and the cool temperature and the thermostat will automatically switch from heat to cool.
